Di-(2-Propyl Heptyl) Phthalate
Di(2-Propyl Heptyl) phthalate is a phthalate ester plasticizer based
on isomeric C10 alcohols.
It offers flexible PVC compounders higher powder bulk density,
which can enhance extrusion rates and the lower efficiency and
lower density of this plasticizer are said to result in lower cost per
Its weather resistance makes it a strong candidate for outdoor
applications. DPHP boasts better UV stability than most
general-purpose plasticizers, making it especially suitable for
applications like roofing, geomembranes, or tarpaulins. Color
stability and aging performance are particularly good.
DPHP is often used as an alternative to diisodecyl phthalate
(DIDP) because only minor compound changes are needed to
adapt wire formulations for example to DPHP. It similarly matches
DIDP performance in automotive applications.
